Piping Insulation
Do not install the indoor units in a machinery shop or
-
kitchen where vapor from oil or mist flows to the
indoor units. The oil will deposit on the heat
exchanger, thereby reducing the indoor unit
performance, and may deform. In the worst case, the
oil damages the plastic parts of the indoor unit.
To avoid any corrosive action to the heat
-
exchangers, do not install the indoor units in an acid
or alkaline environment.
When lifting or moving the indoor unit, use
-
appropriate slings to avoid damage and be careful
not to damage the insulation material on units
surface.
